Abstract: An apparatus (19) for polishing fiber end faces, each terminated by a plurality of cylindrically shaped ferrule type connector plugs (303). The apparatus includes a platform (50) which includes a plurality of nests (525) each adapted to receive a plug such that a plug end face (29) is disposed adjacent to a polishing surface and such that an end portion of fiber which protrudes from each plug engages the polishing surface. Facilities are provided in each nest for applying forces to each plug (30) which may be varied to control the pressure between each fiber end face and the polishing surface (107) and, if desired, subsequently between each plug end face and the polishing surface. Relative motion between the plurality of plugs (30) and the polishing surface (107) is caused to exist such that the polishing surface (107) is turned rotatably while being revolved about an axis to provide uniformly polished fiber end faces. The apparatus also may be used to contour-polish simultaneously a plurality of plugs prior to terminating optical fibers therewith.

Abstract: A ball valve (10) having improved inherent rangeability comprises a floating ball (14) of conventional design that is rotatable through substantially 90° between a pair of seats (17,18) respectively located adjacent the upstream and downstream sides of the valve within a valve housing. At least one of the seats is a one-piece lubricant-impregnated metal seat (18) configured to provide a concave central surface portion (18a) that makes full-face direct sealing contact with the ball (14), and which defines multiple spaced holes (19) that extend through the seat to increase the fluid-to-metal contact of fluid passing through the seat thereby to reduce the pressure between the upstream and downstream sides of the valve. The pattern of holes may be such as to cause the valve to exhibit an equal percentage of flow characteristic for at least a portion of the ball rotation and/or a linear flow characteristic for at least a portion of the ball rotation. When only one such multiple hole seat is used in the valve, the other seat can be a standard round hole seat, or a slotted seat, or a V-seat. In each case, the direct sealing contact between the ball and the multiple hole seat prevents fluid leakage from the ball bore through any holes in the seat that are covered by a surface portion of the ball whereby the valve exhibits improved inherent rangeability.
